Quick answer
Is $3.19 a good price for 5-50PCS LR521 AG0 Button Batteries SR521SW 379A 379 179 D379 SR63…?

The drop of Nov 3 (to $3.19) hasn't been re-checked in the last 48 hours. Check the price on AliExpress before buying.
$3.19
Today it costs $3.19 on AliExpress. Since Oct 27, 2026, when we started tracking it, it ranged from $3.19 to $3.55. It's the lowest price in 18 days, but it has been at this value since Nov 1, 2026; by our price history that is already the normal price, not a sale.
No drop compared with what we observed over the last 14 days. The store advertises "was $4.76", but that is the store's own claim; we only state discounts our price history proves.
